Long day and its dark, cold and I’m really tired. But, I am gonna go back to the air handler to see if I can find a fuse. If I can, I’ll see if its blown and replace it. The thermostat wires are isolated, none are shorted or are shorting each other out, touching in any way. Theyre also marked with stickers. Why ask me the same questions over and over? Is not that uncompromisable. I mean I didnt think typing the model number’s letters and ‘s were needed to be posted repeatedly. Maybe its difficult to comprehend what I have posted and i will be glad to post the same model numbers that I have already posted. But really y’all, aint we beyond that point?

Hooking up a thermostat Forums Home

This thermostat is designed for a system with five wires — the wire terminations are marked as follows: W – This wire comes from the relay that turns on the heating system. Y – This wire comes from the relay that turns on the cooling system. G – This wire comes from the relay that turns on the fan.

Like many others before us, we decided to swap out our analog thermostat for a nice digital one.

When hooking up a tachometer where do you hook the green wire to? The green wire should be the ignition -. Do not confuse it with the regular ground. Check your manual where to find your diagnostic connector the one they put a jumper on for smog check, and where the diagnostic codes are checked ; it is usually in the engine compartment, or maybe under the steering wheel. Somewhere in or around it there should be the IGN- hookup.

Some other possibility would be to check for the ignition- cable coming out of the distributor that is if you have a distributor. My 91 Toyota has both, but I hooked my tach to the IGN- right besides the diagnostic connector in the engine compartment. That also means be careful with the cable not getting frayed or where you place the screws if you hook the tach to the chassis. I would recommend hooking it to a plastic part of the console, or place it over a rug or rubber glove so that the tach does not touch ground chassis.

How to hook up stereo wiring in a Oldsmobile cutlass? They sell wire kits these days to match the vehicle’s harness to the radio wiring.

Thermostat Wiring Colors Code

What you will learn in Thermostat Wiring Colors Code article: What thermostat wire color is likely to go to which terminal on the thermostat. Basic electrical safety and standards for wiring color The function of each wire terminal on the average thermostat.

All other wires, except the common wire, controls a specific relay or contactor.

You will need to obtain replacement thermostats before you begin. Are you sure that the thermostat is bad? Before you conclude that they need to be replaced you should test them. See the article ‘ Testing Water Heater Thermostats ‘ for more information on how to conduct a test. A common problem that may seem like the thermostat is a bad heating element.

Not quite sure what your problem is? See the article ‘ Troubleshooting Electric Water Heaters ‘ for a complete discussion on all of the water heater problems. Electric Water Heater Thermostat Function The thermostats for an electric water heater serve two important functions. First they are used to set the teperature for the hot water in your tank. Most of the time you should stay with the factory settings. See the article ‘ Hot Water Heater Temperature Settings ‘ for some guidelines and a discussion on the dangers of setting the temperature too high.

The second function is to sense when the water has cooled to the point where the elements need to be turned on to heat the water in the tank. Most hot water heaters only run one element at a time.

How do I hook up 5 wire thermostat

Paul Suarez Karl, We updated this posting today in light of new information we recently received. We are truly sorry for the inconvenience. If you have any questions, please reach out to me directly. Karl Dieter Erdmann cadetheat: Nest thermostats have batteries so as long as you hook up the wires correctly they will work fine. Jimmy I think the RC T does not have the transformer like the and so you have to buy it separately to power the Nest.

Getting on to how the v single pole programmable thermostat evolved, it is a part of the line voltage system.

Technically it is possible to use a smart thermostat such as the Nest with electric baseboard or wall heaters, but we no longer recommend it. We no longer recommend that you attempt to install a smart thermostat to use with our products. We even began the process of bringing new parts and products into our system so we could sell the solution directly. Even though we have performed successful testing with the Lyric and Nest thermostats in our engineering lab, we have concerns about the ongoing reliability and durability of this work around.

We felt there were a growing number of you who were interested in having a smart thermostat or wifi control option with our heaters. In the past we felt this was a good solution. We want to make sure you have the latest information. Thank you for understanding. Looking to hook up a smart thermostat to your wall or electric baseboard heater?

Wiring 2 Radiant Heat Systems to a Thermostat

These high capacity thermostats provide for the greatest number of heaters to be controlled with a single thermostat. The TH is also the slimmest of all our thermostat models. TH is equipped with flexible programming to accommodate all types of schedules, a large and legible LCD screen as well as clearly identified buttons.

Basically, this simply utilizes the back-up heat source many heat pumps have to heat the home without sending a signal to the condenser to run for heat.

I would like to put in a new programmable thermostat but I don’t have enough wires. This is a common problem when replacing a mechanical thermostat or a thermostat powered by batteries. These older thermostats require 4 wires, but newer more sophisticated thermostats require a 5th wire known as the Common wire to power the digital display. There are two ways to add the common wire to a four wire installation: Before starting, we recommend that you take a picture of the original wiring to the old thermostat as reference to help remember what terminal each thermostat wire was connected to.

The easiest and least expensive option is to sacrifice independent control of your indoor fan. At your heating and cooling equipment repeat the same step and move the G terminal wire to the C terminal. At your heating and cooling equipment place a jumper wire from the Y equipment terminal to the G equipment terminal. This will allow the fan to turn on when the thermostat is calling for cooling or heating but it will not give you independent fan control from the thermostat.

How to Wire a Thermostat to Your Furnace Blower

Installation can be tricky Verdict A remote sensor lets the Ecobee3 smart thermostat monitor the temperature in more than one room in your house. And, because my thermostat is located closer to my living room, as soon as it senses that my abode has warmed to 65 degrees, it shuts off the heat, leaving me shivering under my covers. The Ecobee3 thermostat has a clever solution to that problem: A remote wireless sensor that measures the temperature and communicates back to the base unit, telling it when it’s hot or cold enough.

If any of the old paint is going to show you may want to make some touch ups now.

These thermostats, whichever type of thermostat or thermostats you have, require little maintenance. Often, I find that the only thing people know about their AC and Heating systems is how to turn the thermostat on and off. And change the temperature setting. The purpose of this site is to help people go beyond the thermostat.

To learn more about their system as a whole. And not just a dial on the wall that adjusts the temperature when they are not comfortable. We have many other related articles. Use the search feature to the right to help you find other related articles.
